The purpose of this study was to evaluate bone activity at the midpalatal suture that had been biomechanically stimulated by rapid maxillary expansion (RME). A rigid acrylic-bonded expansion device with a maxiskeleton screw was used for RME in three patients who were in three different growth periods. The screw was activated twice a day by 1/4 turns. After(More)
In this study, the amount and direction of displacement of reference landmarks located on the cranial base and face were examined and compared according to the superimposition methods of Björk (method A), Steiner (method B), and Ricketts (method C). The material consisted of cephalometric and hand-wrist films of 40 nontreated growing individuals obtained at(More)
OBJECTIVE To investigate the stability of cranial reference landmarks from puberty through adulthood and to compare the displacement of these landmarks among the superimposition methods of Björk, Ricketts, Steiner, and the proposed tuberculum sella-wing (T-W) reference line. MATERIALS AND METHODS The sample consisted of serial lateral cephalometric(More)
INTRODUCTION In this prospective clinical study, we investigated the effects of rapid maxillary expansion (RME) on the electromyographic (EMG) activities of the anterior temporal and superficial masseter muscles. METHODS The sample included 18 subjects (11 girls, 7 boys; mean age, 12.54 years) with unilateral or bilateral posterior crossbites involving 3(More)
A detailed clinical examination of the parts of the temporomandibular joint can be carried out by means of magnetic resonance imaging. The aim of this study was to examine, with the use of magnetic resonance imaging, the mandibular condyle-disc-fossa relationship in subjects with Class II Division 1 malocclusions who were treated with the Andresen(More)
It is commonly believed that upward/backward forces applied to the condyle by a chin-cap cause temporomandibular dysfunction (TMD). In the current study the long-term follow-up (2-11 years) of patients treated with a chin-cap was investigated regarding signs and symptoms of TMD. The treatment group consisted of 32 individuals who had a skeletal Class III(More)
AIM To examine the muscular response of masseter and anterior temporal muscles to functional orthodontic treatment in skeletal open-bite and deep-bite subjects using electromyography (EMG). METHODS The study sample consisted of 31 subjects (18 males, 13 females) grouped into skeletal open-bite (mean age 12.6 ± 2.5 years) and deep-bite (mean age 11.6 ± 2.1(More)
INTRODUCTION The aim of this prospective study was to assess temporomandibular joint (TMJ) condyle-disc positions at the sagittal and coronal planes of magnetic resonance images (MRIs) before and after rapid maxillary expansion (RME). METHODS The study included 18 subjects (11 girls, 7 boys) with a mean age of 12.54 years with unilateral or bilateral(More)
INTRODUCTION In this prospective clinical study, we used bilateral temporomandibular joint (TMJ) magnetic resonance images (MRIs) to investigate the condylar response to rapid maxillary expansion (RME). METHODS Bilaterial MRIs of the TMJs of 18 subjects (11 girls, 7 boys; mean age, 12.54 years; range, 9.75-14.8 years) were assessed. All subjects had(More)
OBJECTIVE To examine inconsistencies in the differential diagnosis of open bite. MATERIALS AND METHODS Using visual judgments, a total of 77 anterior open-bite cases in the postpubertal growth period were grouped as either morphogenetic, functional, or combination. The same sample was also grouped as either hyperdivergent, normodivergent, or hypodivergent(More)
